[meteorite-list] The Tucson Show 2003 Video
Hello All! My Tucson Show Video (CDROM-Version) arrived today and I would like to extend my thanks to all who contributed, especially Bob Holmes and John Gwilliam. What a blast that is to see you folks in person and even hear you talking. Even though Geoff has been thoroughly Americanized, his British accent is still undeniable :-) What a thrill to see and listen to Twink and Jim with whom I have been exchanging emails for several years now but we have never met nor talked to one another in person. I also enjoyed Mike Martinez' beaming capacities and Fred Hall's dry humor about (not) finding a (single) meteorite down in Chile ;-) Wouldn't it be even more fun to include the birthday bash party in full swing, and also to include some scenes from Twink's and Jim's barbecue?! How about more details from the Tucson Show itself - the meteorite dealers, their meteorites, etc., etc. ... Already looking forward to the 2004 edition of the video and/or the CDROM version.

[meteorite-list] Chinge/Chinga TKW
Lars Pedersen inquired: I have in different books and websites read both the name Chinge and the name Chinga for the Russian meteorite. What is the official? I have also read about TKW of 80 kg and well over 350 kg. Does anyone have some official numbers? Hello Lars and List, According to the British Catalogue of Meteorites, its official name is Chinga, but there are several synonyms: Chinge, Tannuola, Tannu-Ola, Tchinge, Tschinga, Tschinge, Tuva, Urgailyk-Chinge. R.A. Gallant uses the Chinge version in his articles in Joel Schiff's METEORITE magazine: GALLANT R.A. (1997) Chinge - Murder, Greed, Dumplings, Meteorites (M! February 1997, Pallasite Press 1997, Part I). GALLANT R.A. (1997) Chinge - Murder, Greed, Dumplings, Meteorites (M! May 1997, Pallasite Press 1997, Part II). The 80 kg you mention are from BUCHWALD V.F. (1975) Handbook of Iron Meteorites, Volume 2, pp.461-464: About 30 fragments of individual weights from 85 g to 20.5 kg, and totaling about 80 kg, were found scattered along the Chinge stream in 1912. But much more has been found meanwhile - especially by Ivan Koutirev and his associates, and that's why R.A. Gallant says in one of his articles: ...there is equal uncertainty about an estimated total mass of recovered objects, although it must be considerably more than 350 kilograms ...

[meteorite-list] Slickensides
Bonsoir Michel, hello List, It is still not very clear to me if these features are made in outer space or the result of hard landing. Here are some interesting tidbits: BUCHWALD V.F. (1975) Iron Meteorites (UCLA, 1975, Vol.3, excerpts from pp. 1128): Figure 1629. Sikhote-Alin (U.S.N.M. no. 1708B). A distorted fragment of 1.28 kg produced during the impact with the frozen ground. Slicken-sided surfaces alternate with twisted and ragged portions. The smaller specimen in the U.S. National Museum is a torn fragment of 1.3 kg with ragged edges. It is one out of approximately 200 similar fragments, totaling 300 kg and excavated in 1948 from pit No. 28 (ibid., Volume 1:180, Volume 2:193). The external shape clearly shows how the major fractures formed upon impact and followed the schreibersite-loaded grain boundaries and the schreibersite-troilite inclusions. The fracture faces are rich in distortions and ridged, semi-polished slickensides c r e a t e d a t t h e m o m e n t o f b r e a k u p. Similar heavily gouged surfaces are present on many Imilac samples. BUCHWALD, V.F. (1975) Handbook of Iron Meteorites, Volume 2, p. 643: Henbury Several other specimens show violent deformations like those of No. 882A, e.g., No. 943 of 3.4 kg, which is a flat explosion fragment with razor-sharp edges, locally overturned. This particular specimen has a slickensided surface f r o m s h e a r - r u p t u r i n g, and it is covered by a thin fusion crust formed when it was hurled away from the impact site. The whole specimen is unique but corresponds closely to the numerous Imilac specimens with slickensided surfaces; see page 1398.

Meteoritics 30, 1995, p. 578): A small impact crater has been identified about 8 km north of Chinle, Arizona, on the Navajo Nation. Preliminary studies show that the crater is in a north-south dircection, measuring about 23 x 34 m in diameter, with a depth of about 1.3 m. The impact origin of the crater is identified by its shape, subsurface deform- ation, and an Fe-Ni oxide fragment. We estimate the age to be about 150-250 yr. It doesn't matter whether the structure is buried or deeply eroded. Maybe this one: C. Koeberl, W.U. Reimold, R.A.

[meteorite-list] Columbia Disaster and more tragedy (Off-Topic)
Hello All! When Rand vented his feelings about astronaut Kalpana Chawla's last words to the media, I did not know that I would soon remember his very words. Most of you will know that I am a teacher. Late in the afternoon, I had just returned from a funeral ceremony, I got a call from a teacher collegue who told me that one of our pupils, just 12 years young, had committed suicide by jumping from the second story of the school building. Tomorrow morning at 07:15 hrs our time, we will be given some important information by the principal and the school psychologist before we meet our students, many of whom had to witness this young life dying on the ground floor. What will I tell them, what will they ask, how will they feel? Before this tragic event, I had planned to talk to them and discuss the Columbia disaster. I would like to do both ... and this is why I remembered Rand's words. They can help bridge the gap between both these saddening human catastrophes. What I would like to beg of you, Rand, is the permission to copy your words along with my German translation (which you also find attached for the German-speaking List Members) to use as a sort of stimulus to start a conversation about both the loss of this young life and about the loss of the Columbia crew. RSVP Now, here is once more part of Rand's contribution: In Kalpana Chawla's last words to the media, she described one of her big WOWs of being an astronaut. She told about sitting next to a window of the space shuttle while looking down at our wonderful blue planet and its swirling firmament of clouds. Refocusing, she then saw her own reflection in the shuttle window. Refocusing again, she saw the reflection of the earth in her own eyes. This, she said, was definitely a big WOW. ... The beautiful dark eyes of Kalpana no longer exist, but I can't help believing that the memory of her big WOW is somehow remembered in a plane of existence beyond my comprehension. Yet I continue to try to understand, and as I do, a feeling for humanity floods over me which I can only describe as ... love. In Kalpana Chawlas letzten Worten an die Medien beschrieb sie einen ihrer schönsten Momente als Astronautin. Sie erzählte davon, wie sie ganz nahe an einem Fenster des Raumgleiters saß, während sie hinunterschaute auf unseren wundervollen, blauen Planeten und auf sein sich stetig veränderndes Wolkenfirmament. Als sie dann ihren zur Erde hinabschweifenden Blick wieder auf das Shuttle-Fenster richtete, erblickte sie darin ihr eigenes Spiegelbild. Noch einmal richtete sie gezielt ihren Blick auf das Fenster des Raumgleiters und sah nun das Spiegelbild der Erde in ihren eigenen Augen. Dies, so sagte sie, war defintiv das Allergrößte. ... Die schönen, dunklen Augen Kalpanas gibt es nicht mehr, aber ich möchte einfach glauben, daß die Erinnerung an dieses, ihr zuteil gewordenes großartiges Erlebnis letztendlich irgendwie auf einer Bewußtseinsebene erinnerlich sein wird, die jenseits meines Fassungsvermögens liegt. Und dennoch versuche ich weiterhin, zu verstehen, zu begreifen, und dabei durchflutet mich ein Hochgefühl für unsere Menschheit, die ich nur beschreiben kann als ...

S H U T T L E T R A G E D Y - Jan 28, 1986 Ronald Reagan's Address To The Nation After The Shuttle Tragedy: Ladies and gentlemen, I've planned to speak to you tonight to report on the state of the Union but the events of earlier today have led me to change those plans. Today is a day for mournings and remembering. Nancy and I have pain to the core over the tragedy of the shuttle CHALLENGER. You know we share this pain with all the people of our country. This is truly a national loss. Nineteen years ago almost to the day we lost 3 astronauts in a terrible accident on the ground but we've never lost an astronaut in flight. We've never had a tragedy like this and perhaps we have forgotten the courage it took for the crew of the shuttle but they - these CHALLENGER seven - were aware of the dangers and overcame them and did their jobs brilliantly. We mourn seven heroes: DICK SCOBEE - RONALD McNAIR - MICHAEL SMITH - GREGORY JARVIS - JUDITH RESNIK- ELLISON ONIZUKA - CHRISTA McAULIFFE We mourn their loss as a nation together. The families of the seven we cannot bear as you do the full impact of this tragedy but we feel the loss and we are thinking about you so very much. Your loved ones were daring and brave and they had that special grace - that special spirit that says: 'Give me a c h a l l e n g e and I'll meet it with joy'. They had a hunger to explore the universe and discover its truth, they wished to serve and they did - they served all of us.We've grown used to wonders in this century - it's hard to bedevil us - but the 25 years the US space program has been doing just that; we've grown used to the idea of space and perhaps we forget that we've only just begun - we are still pioneers. They, these members of the CHALLENGER crew were pioneers and I want to say something to the school children of America who were watching the life coverage of this shuttle's take-off: I know it's hard to understand but sometimes painful things like this happen; it's all part of the process of exploration and discovery; it's all part of taking a chance and expanding men's horizons.The future doesn't belong to the faint-hearted - it belongs to the brave. The CHALLENGER crew was pulling us into the future and we'll continue to follow them. I'd always had great faith in and respect for our space program and what happened today does nothing to diminish it. We don't hide our space program, we don't keep secrets and cover things up - we do it all up front and in public and that's the way freedom is and we wouldn't change it for a minute. We'll continue our quest in space, there'll be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here - our hopes and our journeys continue. I want to add that I wish I could talk to every man and woman who works for NASA or who worked on this mission and tell them: Your dedication and professionalism has moved and impressed us for decades and we know of your anguish - we share it. There is a coincidence today that this year 390 years ago, the great explorer Sir Francis Drake, died aboard ship off the coast of Panama; in his lifetime the great frontiers were the oceans and the story later said he lived by the sea, died on it and was buried in it. We today, we can say of the CHALLENGER crew, there dedication was like Drake's: complete! The crew of the space shuttle CHALLENGER honored us for the manner in which they lived their lives. We'll never forget them nor the last time we saw them - this morning - as they prepared for their journey and waved good-bye and slipped the serving bonds(?) of Earth to touch the face of God ...

We were watching the sky and talking about shooting stars when Papa pointed up and said, 'Look, there's one!' recalled McCleve, now 105 and living in Tempe. A long string of sparkling bright light trailed the enormous mass, which McCleve described as similar to a Fourth of July sparkler, only much bigger and more intense. It was heavenly; something that belonged to God's realm, said McCleve. But I was frightened because it was coming straight toward us. Maybe the others were standing up facing the danger, but I was cowering, getting closer and closer to the ground. I saw it explode in the air and send masses of itself in all directions. It was like shrapnel. The noise was the loudest I've ever heard in my life, and when it landed, it shook the ground like an earthquake. After it hit, McCleve's father matter-of-factly remarked, Well, it missed us, then told the children they could wait until morning to go to the landing site.

The isotope data is proving to be very interesting and was announced at the 65th Meteoritical Society meeting. ... and pre-atmospheric sizes of martian meteorites: a) The authors estimate the minimum masses of the martian meteoroids to have been in the range of 150220 kg. b) The 36Cl concentration in Los Angeles is consistent with a meteoroid radius of 2040 cm. c) The 10Be, 26Al, and 36Cl activities in QUE 94201 indicate a pre-atmospheric radius of 2540 cm. d) For Shergotty, Bhandari et al. (1986) obtained from the 26Al concentration an effective radius of ~12 cm of the meteoroid, about half the value of 23 cm calculated by Eugster et al. e) Density of the shergottites, Nakhla, and Chassigny is about 3.23, 3.37, and 3.72 g/cm3. f) Model calculations of the upper limit of the radius of fragments ejected from Mars yield radii of 2 m. Dont these data ring a bell? The next step for meteoriticists (and several people on our List) could be to compare the existing/ recovered masses - especially of documented falls, of course, like Shergotty, Chassigny, Zagami, and Naklha (Watch out, the Nakhla Dog is back in town :-) - to these minimum pre-atmospheric sizes and thus masses. (Model) calculations involving the physics of the falls (heating and ablation, velocity, deceleration, entry angle, strewn field geometry, etc., etc.) might then give us a clue as to if there is still more recoverable material out there. In the case of Shergotty and Chassigny, most if any at all, may have weathered away in the meantime, but Zagami and Nakhla ... Well, we all know that up to 90 % of a meteorites mass is lost to ablation which would be close to Zagamis total recovered mass of about 18.1 kg (well within the 150 - 220 kg interval mentioned by Eugster et al. - 10% = 15-22 kg) but remember the authors say they are minimum masses!

Here we go again - Bencubbin time once more :-) Best regards, Bernd MASON B.

GEHRELS T. (1979) Asteroids (UoA Press, Part VI, Origin of Iron Meteorites, p. 918): There are other metal-rich meteorites with well-analyzed metal. Bencubbin, Weatherford and Mt. Egerton have chondritic levels of Ir (2-3 µg/g) (Kallemeyn et al. 1978; Scott and Wasson 1976). Bencubbin has been identified as an impact-produced breccia. Its metal has low concentrations of volatile siderophiles like Ga and Ge which show a correlation between abundance and condensation temperature. The only known meteorites containing silicate and appreciable metal with non-chondritic levels of Ir are those in iron group IB. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

Tom aka james Knudson inquired: I was wondering if any one knows or has a good idea of how long it took for Sikhote-alin fireball to create all those beautiful oriented individuals? Hello Tom and List, Probably something between 4 and 15 seconds. The Treysa iron was first observed at a height of 83 km, it reached its end point (zone of retardation, Hemmungspunkt) at a height of 16 km and the length of the trajectory was about 81 km. Its initial velocity was 20 km/s (Sikhote-Alin: 14.5 km/s) and the angle between the trajectory and the horizontal 55° (Sikhote-Alin: 41°). I have no information about the length of the trajectory of the S-A iron nor about the height when it was first observed but due to its enormous (pre-atmospheric) mass it penetrated deeper into the atmosphere and probably reached its end point at an altitude of about 5 km. Anyway I guess that it took no longer than about 10 seconds to create all those beautiful oriented individuals.

aziz habibi wrote: what i hope is that this stone turn to be from mercury. so my question for the list as i want here to open a debat, o-isotope anlysis can they say for sur if a stone is from mercury or not?? Hello All, and best regards, Bernd LOVE S.G. et al. (1995) Recognizing mercurian meteorites (MAPS 30-3, 1995, 269-278): Summary and Conclusions The existence of meteorites from Mars and the Moon implies that impact launch of rocks from Mercury is likely. Orbital evolution of such materials to Earth-crossing orbits appears possible, but its efficiency is probably 1% of that computed for Mars (Wetherill, 1984). Scaling to the number of known martian meteorites, we estimate at best a ~ 10% chance that a mercurian rock could exist in current meteorite collections. These odds are low, but they are not zero. As meteorite collections grow in the future, the probability can only improve. We should recall the lesson of the unforeseen lunar and martian meteorites and be prepared to accept Mercury as a potential meteorite parent body. As with meteorites from other planetary bodies, identifying a mercurian meteorite would be problematic (e.g., Lindstrom et al., 1994). Our ignorance of the properties of Mercury complicates the process of identifying a mercurian meteorite but at the same time increases its potential scientific value. We believe that mercurian meteorites originate in the stony outer layers of a differentiated planet. They may possess an unusual isotopic composition. Rocks from Mercury are probably low in volatiles and are derived from a planet with a bulk composition moderately enriched in refractory oxides of Al, Ti, and Ca. Their FeO contents are not more than ~ 5%, and possibly much lower. The ages (~3.7 to ~ 4.4 Ga) of primary mercurian rocks may overlap with those from the Moon, Mars, and the asteroids. Mercurian regolith breccias (the easiest type of rock to recognize as having originated on Mercury) should be rich in micrometeorite craters, exogenic chondritic materials, agglutinates, and impact vapor deposits. They should show a lower solar-wind content than lunar soils of similar maturity, and the implanted gas may be fractionated by interaction with Mercury's global magnetic field. Mercurian surface rocks should contain a uniquely high solar-to-galactic cosmic-ray damage track ratio. Although some information on Mercury's magnetic history, thermal environment, and radar properties is available, it is of questionable utility in identifying mercurian rocks. Launch-induced shock damage in mercurian meteorites may be comparable to or greater than that seen in martian ones, but this constraint is very weak. Applying the above criteria to the currently recognized meteorite groups, we find that none match the predicted properties of mercurian rocks. The groups in which a misclassified mercurian meteorite would be most likely to lurk are differentiated, low-FeO objects such as the lunar anorthosites and the aubrites. Future searches for mercurian meteorites should focus on similar objects. Recognizing mercurian meteorites would be greatly simplified if we had better knowledge of the elemental and mineralogic composition of the planet, which could be obtained with a relatively simple and inexpensive spacecraft mission. Judging from the case of the lunar meteorites, however, confident identification of a mercurian meteorite will probably not become possible until we have obtained detailed analyses - either in situ or in the laboratory - of known samples of the planet. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Boltysh and the dinosaurs
Best Sunday morning greetings, Bernd TYTELL D. (2002) Did a Comet Swarm Kill the Dinosaurs? (Sky and Telescope, Dec. 2002, p. 24): In 1991 a modern scientific whodunit was solved when geologists identified a deeply buried, 180-kilometer-wide crater in the Yucatan peninsula. Now known as Chicxulub, the scar resulted from the impact of a 10-km asteroid or comet nucleus 65 million years ago. Geologic evidence indicates that the impact triggered global tidal waves, world- dwide firestorms, and massive earthquakes. It also left a worldwide layer of extraterrestrial dust. When Earth finally returned to normal, the dinosaurs and the majority of all then-living species had gone extinct, opening the way for mammals to diversify and dominate Earth. Now a new study suggests that Chicxulub may not have been an isolated event. Rather, the dinosaurs may have been the victims of a one-two punch. Simon P. Kelley (Open University, UK) and Eugene Gurov (National Academy of Ukraine) have reexamined the age of a much smaller, 24-km-wide crater buried in Ukraine and known as Boltysh. As recently as 1993, geologists estimated the impact to be 73 million years old. However, through a number of isotopic experiments, Kelley and Gurov have refined that date to 65.2 ± 0.6 million years. By comparison Chicxulub's age is 65.5 ± 0.6 million years. The overlapping uncertainties suggest that the two impacts may have occurred simultaneously or nearly so. Kelley believes a Boltysh-size crater should appear at random every 1.8 to 3.3 million years. So it would be somewhat unlikely for an unrelated impact to be so close to Chicxulub's age. The trouble is that with only two craters, random impacts are not outside the realm of possibility, says Kelley. Despite his published range of errors, I would be fairly confident that there was only a 250,000 year difference [between Chicxulub and Boltysh], he says, adding that he thinks a link is highly probable. What's more, Earth's surface is approximately three-fifths water. Therefore, if two related objects did hit land, roughly another three should have splashed down in the oceans. However, the seafloor bears no obvious trace of these - they would have been subducted into the mantle long ago. If the dinosaurs did indeed endure multiple hits, scientists might be able to say something about the nature of the impactors. Asteroids tend to travel alone (though pairings do exist), while comets are thought to sometimes arrive in bunches. A gravitational disturbance in the Oort Cloud or Kuiper Belt - the massive comet reservoirs at the outer reaches of our solar system - could jostle a swarm of dirty snowballs inward toward the Sun and Earth. Such impacts could come hundreds of thousands of years apart. Another possibility is a single comet that broke into pieces after passing too near a planet (the fate of Comet Shoemaker- Levy 9). Such impacts would happen close together. Chicxulub was still the big killer, however. The sizes of the two craters imply that Boltysh hit with only about 1/100 as much energy. Kelley's next step is to derive isotopic ages for other craters with roughly comparable ages. Many craters have been dated merely by strati- graphic evidence, which is less accurate than using an isotopic chrono- meter. Perhaps additional, theory-clinching 65-million-year-old craters exist and have simply been assigned the wrong age. Boltysh's assumed age was in error by some 8 million years; others could be off by that amount or more. Kelley and Gurov present their findings in the August issue of Meteoritics and Planetary Science. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] A Recent Asteroid Crackup
A Recent Asteroid Crackup (Govert Schilling) Planetary scientists have identified fragments from a solar-system smashup that happened only 5.8 million years ago - just yesterday, cosmically speaking. That appears to be when a main-belt asteroid about 25 kilometers across was shattered by a much smaller body striking it at 5 km per second. So far there are 39 known fragments from this crackup; the largest, 832 Karin, is 19 km wide. David Nesvorný (Southwest Research Institute, Boulder, Colorado) and three colleagues found the cluster by carefully sifting through tens of thousands of minor-planet orbits to isolate those with similar semimajor axes, eccentricities, and inclinations. Then, by extrapolating the slowly changing orientations of 13 of these orbits backward in time, the team found that they were all aligned with each other 5.8 ± 0.2 million years ago - presumably the fateful date when their parent body was smashed to pieces. The Karin cluster is part of the much larger Koronis family. How- ever, in this and other older family associations, the orbits have been changed too much by subsequent collisions, gravitational disturbances, and radiation pressure to be traced back to a common origin. This new cluster will no doubt be the focus of attention for the asteroid community for some time, writes Derek C. Richardson (University of Maryland) in the June 13th issue of Nature.

[meteorite-list] 1880 German Encyclopedia of Astronomy
For Your Reading Pleasure :-) Meteorites: Meteorites are those small celestial bodies that orbit the Sun in closed orbits both as single bodies as well as large cloud-like agglomerations. The Earth's orbit intersects several of these meteoric orbits and it is then that these small bodies occur as falling stars or bolides (lit by friction in the Earth's atmosphere) and fall to the Earth's surface as meteoric stones provided that the direction of their course causes them to do so. As their content in iron is mostly considerable, the selfsame are also called meteoric irons. From August 10 till August 13 and around November 12, the Earth wanders through meteoric clouds, and the shooting stars of August are called Perseids, those of November Leonids, because the former emanate from the constellation Perseus, and the latter from the constellation Leo. After a period of 33 years, the Leonids fall in such large numbers that they completely illuminate the sky during several hours of the night.

Aziz Habibi a écrit: hello everyone Bonsoir Habibi, hello List, happy to be in the meteorite central writing to you Bienvenue - welcome to our List! many collectors and honest dealers ask me to write to the mailing list Une bonne idée - a good idea! well my objectives are in one way to find good offers La plupart d'entre nous a déjà admiré les beautés que tu offres aux enchères EBAY (NWA 1110, Ouzina, et une eucrite) mais ne vaudrait-il pas mieux en offrir des tranches plus petites afin que les collectionneurs de tous les jours puissent s'en offrir un petit peu? Most of us have been admiring the beauties you are offering on EBay (NWA 1110, Ouzina, and a eucrite) but wouldn't it be better if you offered smaller pieces that are more affordable for the average meteorite collector? Jamais de ma vie pourrais-je m'offrir une météorite qui coûte $ 45,000. Never in my life would I be able to purchase a meteorite that costs $45,000 :-( as we are never payed enough for the work we do in nwa Absolument d'accord! I absolutely concur! i will try the next month to show you all what we found in the sahara in nwa with the ligitime hunter and founder.

Ken wrote amused: Mark, I really enjoy the old newspaper articles. They invariably raise more questions than they answer. Like how does a 25 lb object gradually worked to the surface by itself? Ken, you gotta read that twice!

[meteorite-list] Murchison Amino Acids
Jonathan inquired: Does anybody know the names of the unidentified amino acids in Murchison? Do they even have names? Hello Jonathan and List, Just in case you wonder why nobody has responded yet. I think this is due to an unwritten law that we should not poach in someone else's game preserve :-) The undisputed expert in this field has always been Greg Shanos, so I guess everyone is waiting for him to chime in. Yoohoo, Greg, where are yoo? Bernd __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

Hello Bob and List, What a pity the pictures are only black and white - especially in view of the well-preserved fusion crust and the sawn surface showing these breathtaking, long pyroxene needles (several millimeters)! The cut surface almost looks like a cut and etched piece of Taza with its fine kamacite needles. Oh, by the way, Carine Bidaut is mentioned as Carine Bidant :-) Bernd __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Virus Problems
Hello Tom, Jonathan, and List, I got these multiple emails too - just like Matteo and many others. Absolutely necessary first step: keep virus protection updated (Norton, MacAfee, etc.) First anti-step: D E L E T E Second anti-step: No direct response - that's why I don't use Tom's email he sent a few minutes ago. You will already have noticed that I usually add information about attachments in my subject lines - example: BL# 18 - 3 JPEGs (xxxKB). The recipient will then be able to compare what I sent with what he got. An additional safety measure is to accurately describe in your posts and/or mails what you are sending - example: I am attaching a Microsoft Word document called It comprises xxx KBs... What makes Jonathan's unintentional (!) posts so very suspect is the word boot. We all know how much damage a virus can do to our boot sectors. Knocking on wood because, so far, I have never had the bug ... or have I :-( ??? Anyway, Jonathan, keeping my fingers crossed for you!!!

Re: [meteorite-list] eBay item 721721230 (Ends Oct-16-02 185935 PDT ) - Coursest Iron Meteorite 2608
Tom / james Knudson wrote: Have you all seen this unknown Iron? What do you all think it is? Wow! What a beautiful piece - it even seems to have a heat-alterated alpha-2 zone! We might know more about its provenance if we knew exactly the bandwidth of the Widmanstaetten lamellae. So, Tom, why not ask the seller? The more accurate the information about its band- width, the better the chance to find out more!
